Abstract: The inorganic cation exchangers according to the invention are constituted by acid phosphates or arsenates of tetravalent metals in solid solution with each other or with part of the phosphate or arsenate groups substituted by phosphite groups. 
     The process for preparing cation exchangers containing phosphite groups comprises reacting in the aqueous phase a compound of a tetravalent metal with one of the following pairs of acids: phosphoric-phosphorous and arsenic- phosphorous. Crystallisation has been obtained by boiling under reflux, by heating in an autoclave to a temperature of less than 300°C, and also by conducting the reaction in the presence of a complexing agent for the tetravalent metal.

Abstract: Matrix arrays, in particular infra-red arrays, suffer from non-uniformity in output from the individual elements in the array. This is due to each element in the array having for example, its own characteristic responsivity and leakage current, and is seen in the array output as a pattern of offset values. These offset values must be removed from the output of the array if useful digital information is to be obtained. One known method of doing this is to show the array a black body at a known uniform temperature and use the output from the array to cancel the offset values. However, the dynamic range of the system is directly related to the range of offset values obtained and also to the size of the digitiser. Large-size digitisers have relatively slow sampling rates and in order to have a higher sampling rate, a small-size digitiser must be used. The signal processing system described herein corrects for offset values and is able to provide a high sampling rate by using a small-size digitiser.

Abstract: A method and apparatus are described for refrigeration according to a refrigeration cycle wherein a working fluid is evaporated in a generator (11) at high pressure, the working fluid vapor is expanded and formed into a vapor stream entraining working fluid vapor from an evaporator (13), the vapor stream is condensed to a liquid, a part of the condensed liquid is returned to the generatore (11) for evaporation at high pressure, and another part of the condensed liquid is expanded and passed to the evaporator (13) for entraining in the vapor stream. According to the novel method and apparatus, the entrainment of the vapor in the vapor stream is enhanced by increasing the pressure of the vapor from the evaporator before the vapor is entrained in the vapor stream. This has been found to significantly improve the Coefficient of Performance (C.O.P.) of the refrigeration cycle.

Abstract: An image generator for generating two-dimensional images of three-dimensional solid objects at a high speed defines a scene to be displayed within a cuboid three-dimensional universe which has been hierarchically subdivided into a plurality of discrete volumes of uniform size and similar orientation. The three-dimensional universe is represented by a tree structure having a plurality of nodes, one for each volume in the three-dimensional universe which is at least partially occupied by objects in the scene. A user may select a point of view for viewing the object. Nodes in the tree structure representing the three-dimensional universe are visited in a sequence determined by the point of view selected by the user so that nodes corresponding to volumes which are unobstructed by other volumes are visited first. Each visited node which is enclosed by the object is projected onto a subdivided view plane organized into a hierarchy of a plurality of discrete areas. Areas of the view plane which are completely enclosed by the projection are painted onto a display screen. Areas which intersect but are not enclosed by the projection are further subdivided to locate those areas which are enclosed. A representation of the hierarchically-subdivided view plane arranged in a tree structure is stored in a store. Each time an area of the view plane is painted, an entry in the representation of the view plane corresponding to that area is marked. The corresponding entry in the representation of the view plane is checked before an area is painted, to ensure that no area is painted more than once so that hidden surfaces are not displayed. To create sectional views, a user may define a region of the three-dimensional universe, and volumes outside of that region are not projected. Due to the hierarchical structure of the three-dimensional universe and the two-dimensional view plane, the symmetry of subdivisions, and the resulting simplicity of the calculations necessary to create an image, real time image generation wherein calculations necessary to create the image are performed by hard-wired digital logic elements to increase speed performance is possible.

Abstract: A fast Fourier transform is performed under control of stretched out microcode. Sequential data inputs are multiplied by coefficients addressed by microcode in a digital multiplier (30). The resultant products are sequentially stored in three registers (38, 40, 42). The product stored in the second register (40) is applied as one input to an arithmetic logic unit and the product stored in either the first or the third register (38, 42, respectively) is applied as the second input to the logic unit in order to compute the operation pairs (ax ± by). The Fourier transform is based on Winograd Fourier transforms modified for only real inputs and to force operations into the form (ax ± by). Sample points are initially scaled using the same circuit by performing an OR operation with respect to each sample point and an accumulated OR taken from the output of the ALU. The position of the most significant one bit in the final accumulated OR is indicative of the required scale factor. That scale factor is applied to the multiplier to scale each sample point.
